TECHNICAL FIELD

The present disclosure relates to a robotically-operated painting andcleaning system. More particularly, the present disclosure relates to arobotically-operated spraying system that can be used for spraying wallsurface of a building for purpose of painting and/or cleaning.

BACKGROUND

It is well known in the art to use a moveable carrier suspended bycables from atop a building for painting and cleaning an wall of thebuilding. In some cases, these moveable carriers may be sized largeenough to accommodate painters and/or cleaner therein who would then setup to manually paint the wall of the building. With use of suchlarge-sized carriers, structures required to support the carriers wouldneed to be sturdy enough to withstand the weight of the carrier inoperation besides minimizing the tendency of the carrier to sway underthe undesired effect of wind forces. An example of a sturdy mechanismfor suspending such large sized carriers is disclosed in U.S. Pat. No.3,347,339.

Nevertheless, in recent times, a size of these moveable carriers hasbeen reduced with implementation of automated robotic mechanisms thatare capable of performing the painting and cleaning operations. However,with incorporation of such automated robotic mechanisms, it would onlybe prudent to additionally render these moveable carriers with enhancedstructural and performance capabilities that would facilitate movementof the carriers and the automated robotic mechanisms disposed within totraverse the span of the wall surfaces in an optimal or efficient mannerand carry out the operations synergistically.

Thesystem 100 includes a pair of rails 102, 104 disposed on an upperportion 204 of the building 200. A first one of the rails 102 isconfigured to slidably support movement of at least one frame member 106thereon. In an example, two frame members 106 are shown in theillustrated embodiment of FIG. 1. However, it may be noted that fewer ormore frame members 106 may be implemented depending on specificrequirements of an application including, but not limited to, astructural integrity of the frame member that is required to performfunctions consistent with the present disclosure.

For avoidance of doubt, the system 100 adapts a spraying mean, which canbe used for spraying paints and/or clean water for cleaning wallsurface.

The frame member 106 has a primary motor 108 mounted thereto forfacilitating lateral movement of the frame member 106 along a length Lof the first one of the rails 102. The system 100 also includes acarrier 110 suspended from the frame member 106 by cables 112 that aresupported on pulleys 114 associated with the frame member 106. In anembodiment as shown in FIG. 1, each frame member 106 includes a free end116 that is engaged with a second one of the rails 104. The free end 116of each frame member 106 is associated with a pre-determined weight 118to counterbalance a weight of the carrier 110. Also, the system 100further includes a tow line 120 connecting the carrier 110 to a groundsurface 122. The tow line 120 is configured to stabilize a position ofthe carrier 110 in relation to the wall 202.

In one embodiment, the carrier 110 can be a gondola carrier.

In a further embodiment as shown in FIG. 1, the system 100 additionallyincludes at least one wheel 124 disposed on the carrier 110 and locatedin an opposing relation to the wall 202. The wheel 124 is configured toassit when the carrier is maneuvering by the wall 202.

The carrier 110 is adapted to accommodate a secondary motor 126, avisual monitoring system 128, a robotic mechanism 130, a computingdevice 132, and a controller 134 therein. The secondary motor 126 isengaged with the cables 112 to facilitate movement of the carrier 110 ina direction D parallel to a height H of the wall 202.

The visual monitoring system 128 is configured to scan structuralcharacteristics and profiles of the wall 202 through digital imagingtechniques. In one embodiment, the visual monitoring system 128 mayinclude a 3-dimensional camera. In another embodiment, the visualmonitoring system 128 may include a 3-dimensional laser scanner.

The robotic mechanism 130 has an end effector 136 that is adapted tosupport a spray nozzle 138 thereon. In an embodiment of this disclosure,the robotic mechanism 130 has six degrees of freedom in movement forfacilitating the spray nozzle 138 in spraying the wall 202 of thebuilding 200.

FIG. 2 illustrates a schematic representation of components of thesystem 100 from FIG. 1. As shown in FIG. 2, the computing device 132 isdisposed in communication with the visual monitoring system 128, theprimary motor 108, the secondary motor 126, the robotic mechanism 130,and the spray nozzle 138. The computing device 132 is configured toreceive the scanned structural characteristics of the wall 202 from thevisual monitoring system 128. The controller 134 is communicably coupledto the computing device 132 and is configured to independently controloperation of respective ones of the primary motor 108, the secondarymotor 126, the robotic mechanism 130, and the spray nozzle 138 inresponse to the sensed structural characteristics and profile of thewall 202.

In an additional embodiment as shown in FIG. 1, the system 100 alsoincludes multiple linear actuators 140. Each of the linear actuators 140is slidably engaged with the carrier 110. The system 100 also includes asuction cup 142 located at a free end 144 of each linear actuator 140and disposed in an opposing relation to the wall 202 of the building200. The suction cups 142 are configured to selectively adhere with thewall 202 of the building 200 for positioning the carrier 110.

In an embodiment, at least one of the sensed structural characteristicsof the wall 202 includes a distance between each suction cup 142 and thewall 202. As shown in FIG. 2, the system 100 further includes ultrasonicsensors 146, disposed on the carrier on two sides, associated with eachof the linear actuators 140 shown in FIG. 1. Each of the ultrasonicsensors 146 is configured to output a distance of the associated suctioncup 142 relative to the wall 202, to the computing device 132 which inturn provides such outputs to the controller 134. Accordingly, thecontroller 134 is configured to selectively and independently actuatemovement of each of the plurality of linear actuators 140 untilrespective ones of the suction cups 142 adhere with the wall 202 of thebuilding 200.

In the case where the system 100 is adapted for spray painting, in anembodiment, a paint container 148 is disposed within the carrier 110.Further, as shown in FIG. 2, the system 100 includes a sensor 150 thatis disposed in communication with the paint container 148 and thecomputing device 132. The sensor 150 is configured to output a level ofpaint remnant in the paint container 148 to the computing device 132.

In the case where the system 100 is adapted for spray cleaning throughhigh speed water jet, the spray nozzle may be connected directly to awater source through water hose. A person skilled in the art wouldappreciate that the system may require a stronger pump and/or nozzle maybe required for cleaning purposes. The carrier can also include acontainer for loading liquid detergent to aid in the cleaning process.

Additionally or optionally, as shown in FIG. 1, the system 100 furtherincludes a hood 152 be disposed around the spray nozzle 138 as shown inthe illustrated embodiment of FIG. 1. The hood 152 is configured tocontain sprayed liquid that escapes from being sprayed onto the wall202.

In a further embodiment, the hood can be any overhead covering meansdisposed at on the front end of the spraying tip for assisting inisolate overspray and fumes of the sprayed liquid. It is well understoodto a skilled person that there can be many forms of geomatry applicableto the hood. In yet a further embodiment, the hood can be adapted withbarn doors.

In another embodiment, the computing device 132 may be remotelycontrollable with the help of a remote controller 158 shown in FIG. 2.It is envisioned that with use of the remote controller 158, anyfunction pertaining to individual components of the system 100 can becontrolled wirelessly by a remotely located operator via the remotecontroller 158. Therefore, it may be noted that although the system 100of the present disclosure is configured to operate autonomously with thehelp of data from the ultrasonic sensors 146, the paint level sensor150, and the visual monitoring camera, embodiments of the presentdisclosure also allow an operator of the system 100 to remotely overrideany operations and provide alternative commands to the computing device132 with the help of the remote controller 158 so that the computingdevice 132 may appropriately control one or more components of thesystem 100 in accordance with the alternative commands provided by theoperator.

Referring to FIG. 3 and as disclosed earlier herein, the computingdevice 132 is communicably coupled to each of the controller 134, theprimary motor 108, the secondary motor 126, the inclinometer device 162,the visual monitoring system 128, the ultrasonic sensor 146, each of thelinear actuators 140, a valve mechanism 154 shown in FIG. 1 as beingassociated with the spray nozzle 138, and the robotic mechanism 130.

Moreover, as shown in FIG. 3, the computing device 132 is developed on arobotically-operated software (ROS) platform that is configured toinclude a carrier positioning module 302, a spraying module 304, avision module 306, a motion module 308, and a graphical user interface(GUI) module 310. Further, the computing device 132 on which the ROSplatform resides would also be configured to include a program managermodule 312 that is disposed in communication with each of the carrierpositioning module 302, the spraying module 304, the vision module 306,the motion module 308, and the GUI module 310.

As such, it may be understood that the carrier positioning module 302may be disposed in communication with the controller 134, the primarymotor 108, the secondary motor 126, and each of the linear actuators140. The carrier positioning module 302 may also be disposed incommunication with one or more sensors disclosed herein, for example,the inclinometer device 162, the ultrasonic sensors 146, and the like,that are associated with operation of one or more of the primary motor108, the secondary motor 126, and each of the linear actuators 140. Thecarrier positioning module 302 therefore, may be configured to receivedata from such sensors to help the program manager module 312 inaccomplishing the positioning of the carrier 110 appropriately withrespect to the wall 202 of the building 200.

Further in the case of spray painting, the spraying module 304 may bedisposed in communication with the liquid level sensor 150 and the valvemechanism 154 of the spray nozzle 138. The spraying module 304 mayreceive data from the liquid level sensor 150 transmit such data and/orfeedback to the program manager module 312 for determining the level ofpaint remnant in the container 148 and for operating the valve mechanism154 of the spray nozzle 138 to spray on the wall 202 of the building200.

Furthermore, the vision module 306 would be disposed in communicationwith the visual monitoring system 128. The vision module 306 can receivedata including the sensed structural characteristics of the wall 202from the visual monitoring system 128 and provide the same to theprogram manager module 312. This data could help the program managermodule 312 to independently control a movement of each of the linearactuators 140 and adhere the suction cups 142 on the wall 202 of thebuilding 200 for stabilizing a position of the carrier 110.

Still further, the motion module 308 may be disposed in communicationwith the robotic mechanism 130, and particularly with the end effector136 of the robotic mechanism 130. The motion module 308 may receivefeedback from the robotic mechanism 130 and send such feedback to theprogram manager module 312 so that the program manager module 312 canplan a trajectory for movement of the end effector 136 of the roboticmechanism 130 so that spraying can be commenced on the wall 202 of thebuilding 200 upon stabilizing the position of the carrier 110.

It is to be noted that the modules 302-312 explained in the foregoingdisclosure is non-limiting of this disclosure. Rather, other types ofmodules may be, additionally or optionally, implemented in addition toor in lieu of the positioning module 302, the vision module 306, thespraying module 304, the motion module 308, and the GUI module 310 toco-operate with the program manager module 312 without deviating fromthe spirit of the present disclosure as will be evident from theexplanation pertaining to the working of the system 100 which will bemade in detail hereinafter.

In an alternative embodiment to the system 100 depicted in FIG. 1, thesystem 100 may, as shown in FIG. 4, additionally, or optionally, includea stabilizer platform 1102 that may be disposed below the carrier 110and moveably connecting to the carrier 110 through a connecting bar1111. The stabilizer platform 164 may include therein, a drive systemthat is moveably engaged to the connecting bar 1111, and at least onesecondary suction mechanism 1106 that is similar to or different fromthe suction cup 142 of the carrier 110. The drive system 1104 may becommanded to operatively position the stabilizer platform 1102 relativeto the carrier 110. Additionally, the secondary suction mechanism 1106could also be commanded for adhering with the wall 202 of the building200. When the secondary suction mechanism 1106 adheres to the wall 202of the building 200, the secondary suction mechanism 1106 provides addedresistance to the carrier 110 from swinging into or away from the wall202 of the building 200.

During operation, it is envisioned that if the carrier 110 is to bemoved e.g., downward along the height H of the building 200, then thesecondary suction mechanism 1106 is first released from adherence withthe wall 202 and thereafter, the drive system 1104 is commanded tooperably move the stabilizer platform 1102 downward along the height Hof the building 200. Once the stabilizer platform 1102 is moved to apredetermined or anticipated position in relation to a position at whichthe carrier 110 needs to be subsequently moved into, the secondarysuction mechanism 1106 would be commanded to adhere with the wall 202 ofthe building 200 before commanding the secondary motor 126 to move thecarrier 110 into its subsequent position. Therefore, in this embodiment,it may be noted that at any given instant of time, either the secondarysuction mechanism 1106 associated with the stabilizer platform 1102 orthe suction cups 142 from the carrier 110 are in adherence with the wall202 of the building 200. As the carrier 110 and the stabilizer platform1102 connected through the connecting bar 1111 and are also disposed onthe same set of cables 112, forces, for example, undesired forcesassociated with wind, that could otherwise displace the carrier 110 aremitigated by the adherence of the secondary suction mechanism 1106and/or the suction cups 142 and in this way, the gondola carrier 110could be resisted from swinging into or away from the wall 202 of thebuilding 200 while it is “crawing” along the vertical wall 202.

Also, as shown in the illustrated alternative embodiment of the system100 in FIG. 4, the system 100 may further include a linear track 1108located above the carrier 110 and disposed horizontally with respect tothe height H of the building 200. A length L1 of the linear track 1108may be selected such that the linear track 1108 would be configured toextend at least up to a width W of the carrier 110. The roboticmechanism 130 may be slidably disposed on this linear track 1108, and inoperation, the robotic mechanism 130 may be commanded to traverse thelength L1 of the linear track 1108 so as to be axially displaceable inposition. The linear track 1108 can offer a greater range of movement tothe robotic mechanism 130 as it allows the robotic mechanism 130 to bepositioned at any desired point along the length L1 of the linear track1108. This way, when spraying operation is in process, a reach of theend effector 136 may be enhanced to cover a greater surface area of thewall 202 in a single pass of the carrier 110. Also, with greater reachof the end effector 136, a number of times for which the frame 106 wouldotherwise need to be moved along the rail 102 can be potentiallyminimized to reduce an overall cycle time associated with re-positioningthe carrier 110 for spraying the wall 202 of the building 200.

Referring to other alternative embodiments depicted in FIGS. 5 and 6,the carrier 110 may be a scissor lift arrangement 1202 as shown in FIG.5 or a boom lift arrangement 1302 as shown in FIG. 6 respectively. Thescissor or boom lift arrangements 1202/1302 can be used in lieu of thecables 112 and the secondary motor arrangement 126 to operably vary aheight to which the carrier 110 is moved in relation to the groundsurface 122. In fact, the scissor lift arrangement 1202 and the boomlift arrangement 1302 may allow the gondola carrier 110 to not only beused in accomplishing a spraying of the wall 202 of the building 200(shown in FIG. 1) but also in spraying an interior wall 206 of thebuilding 200.

It is understood to a skilled person that the system 100 in accordancewith the present invention is adapted for mounting on any aerial device,such aerial work platform, elevating work platform or the like.

In yet a further embodiment of the present invention as shown in FIG. 7,the robotic mechanism 130 is mounted on a two-ways track system 1400allowing the robotic mechanism 130 be moving in at two axes directions,i.e. both longitudinal and lateral directions. As shown, the two-waystack system 1400 comprises a lateral track 1402 slidably attached on alongitudinal track 1404. The robotic mechanism 130 is slidably mountedon the lateral track 1402 allowing the robotic mechanism 130 be movingalong the length of the track, while similarly, the lateral track 1402that mounted on the longitudinal track 1404 allows the robotic mechanism130 movable along the length of the longitudinal track 1404.Accordingly, the two-ways track system 1400 extends the movability ofthe robotic mechanism 130 on the vehicle (including gondola) on which itis mounted.

In another embodiment, the two-ways track system 1400 can be adapted asa H shape track having a longitudinal track disposed between two lataraltracks. The two way track system 1400 can be mounted on any vehicles,such as gondola, boom lift, scissor lift or the like.

With the various configurations offered by the embodiments of thepresent invention, it is well understood to a skilled person that spraysystem can be used for external wall as well as internal wall when it ismounted on a suitable vehicle. By replacing the nozzle head withinspection means, the present system can also be used to automate wallinspections.
